Cochlear Implants: The process behind cochlear implant surgery

The video tutorial explains the process of cochlear implant surgery, focusing on the electrode array and its insertion into the cochlea. It describes the surgical steps, including making an incision, creating a pocket for the implant, and performing a mastoidectomy. The video highlights the delicate nature of the procedure, especially around facial nerves, and the importance of secure electrode connections. It concludes with the healing process before adding the external transmitter.

What is the primary function of the electrode array in a cochlear implant?

• To amplify sound

• To transmit sound waves

• To stimulate the auditory nerve

• To protect the cochlea

During the cochlear implant surgery, why is it important to work around facial nerves?

• To prevent facial paralysis

• To improve electrode function

• To reduce surgery time

• To enhance sound quality

What is the purpose of a mastoidectomy in cochlear implant surgery?

• To access the facial nerve

• To remove the cochlea

• To place the external transmitter

• To insert the electrode array

How many electrodes are typically used in a cochlear implant to aid hearing?

• 30

• 22

• 10

• 50

What is the next step after the electrodes are implanted in the cochlea?

• Testing the implant

• Adding the external transmitter

• Patient healing

• Immediate activation of the device
